Paul (Greg Kinnear) and Jessie Duncan (Rebecca Romijn-Stamos) have barely begun the grieving process when Dr. Richard Wells (Robert De Niro) attends the funeral of the Duncans' eight-year-old son, Adam (Cameron Bright), with a pressing question in tow. Head of the Godsend Fertility Clinic, Dr. Wells claims he can use Adam's rapidly dying cells to clone a replica of the boy, though the necessary DNA will only be viable for another 24 hours. The process in itself is completely illegal; not only must Jessie and Paul be forced to relocate, but they will also be forced to sever all ties with friends and family in order to ensure the secret remains so. Within the space of a day, the Duncans consider the legal and ethical implications of such a procedure, ultimately deciding that their love for Adam is enough to trump the law and any high-minded philosophical questions. After resettling in an idyllic town near Dr. Wells' clinic, Jessie is impregnated with the late Adam's living cells, while Paul is given a beautiful home and a more than suitable job. Shortly afterward, the new Adam -- seemingly identical to the original Adam in every way -- is born and lives a life quite similar to his predecessor until the morning of his eighth birthday. A series of night terrors is the first thing to disturb the Duncans' otherwise serene lifestyle. Adam's violent visions eventually mutate to ill temper, and an aura of menace permeates the aura of a boy who had otherwise been sweetness incarnate from the day of his birth. Eventually, Paul discovers that Dr. Wells is not a pediatrician, but a geneticist, and that their playing God may have been a Faustian bargain of epic proportions.
